Sure Shot sprayers are an inexpensive way to apply bulk chemicals like cleaners, degreasers, penetrating oils, solvents, and lubricants. They use readily available compressed air instead of flammable and/or dangerous propellants, and because they are reusable, you don't have to worry about the disposal of empty cans. Manufactured since 1932, Sure Shot is the leader in Refillable, Rechargeable, completely portable compressed air sprayers.
